what you say is off course all very true, but there is an adder in the
grass: this is only when all wiring in the system is done according to the
rules!!!
And I assure you that the UPS is NOT. Oterwise these problems would not
exist.
So personally I would like to blame the earth wire all the

It's unlikely, but no harm in ruling it out.

anyone got any advice re. shielding. All signal cable screens are grounded to
